The present invention relates to a window guard and has for its object to provide a structure which is strong and durable and may be easily and quickly installed in a window frame.

Another important object of the invention resides in the provision of a window guard of this nature which is simple in its construction, inexpensive to manufacture, thoroughly efficient and reliable in use and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is an elevation of a guard embodying the features of my invention showing the same installed in a window frame.

Figure 2 is a detail sectional view showing the fastening means, I

Figure 3 is a sectional view taken substantially on the line 33 of Figure 2.

Figure 4 is a fragmentary top plan view of one of the channel bars, Figure 5 is an elevation of one end of another embodiment of the channel bars showing the same associated with a stone frame which is illustrated in section.

Figure 6 is a sectional view taken substantially on the line 6--6 of Figure 5,

Figure 7 is a bottom plan view of one end of the bar.

Figure 8 is an elevational View of a modified form of guard.

Figure 9 is a perspective view of an upright forming part of the invention shown in Figure 8 and Figure 10 is a fragmentary perspective view of an inverted channel bar, certain parts being broken away to illustrate details of construction to be hereinafter more fully referred to.

Referring to the drawings by reference nu- 45 morals, reference being had particularly to the form of the invention shown in Figure 1, it will be seen that the numerals 5 denote a pair of inverted channel bars provided intermediate their ends with a plurality of longitudinally ex- 0 tending slots 6. Numerals '7 denote a plurality of uprights which are formed from elongated bars, rectangular in cross section. and have right and left hand twistedend portions 8 threaded through the slots 6.

This arrangement will permit the horizontal bars 5 to be adjusted on the vertical bars '7 to place the straight central portions of the bars 7 in the slots 6 so that the bars 5 can be tilted to place their ends in the grooves of the window frame, after which the bars 7 are turned to position them, as shown in Figure 1. The guard is removed from the window frame in the same manner after the ends of the bars 5 are released from the sides of the frame. Thus this arrangement renders it unnecessary to weld or otherwise connect the bars 7 with the bars 5 or to provide slidable means at the ends of the bars 5 for adjusting said bars to make their ends engage the grooves of the frame.

In the embodiment of the invention shown in Figures 1 to 4 inclusive the bars 5 are provided at their ends with transverse slots 9. Substantially S-shaped clips 10 have portions extending through the slots 9 so that the major portions of the clips are below the bars 5 and are provided with openings 11 to receive screws 12 for anchoring the bars in the window frame and then the lower end portion 10. of each clip is bent up over the head of the screw.

In theembodiment shown in Figures 5, 6 and '7 it will beseen that the channel bars 5' are provided at their ends with depending clips or ears 14 which are formed with openings through which are projectable elongated pins 15 to extend into recesses 16 of a stone frame or the like 17. The ends of these pins under the bar 5 are formed with eyes 18 riveted as at 19 to the bar 5.

In the form of the invention shown in Figures 8 to 10 inclusive it will be seen that the guard comprises a pair of inverted channel bars 5a connected at one end by an upright 20. At their free ends the channel bars 5a, which bars are provided with oppositely disposed internal grooves 21 are adapted to slidably receive relatively short bar sections 22 provided on an upright 23.

The bar sections 22 are provided on relatively opposite sides thereof with ribs 24 slidably engageable with the grooves 21. Each of the bar sections 22 has suitably mounted thereon aconventional key controlled lock 25 of the barrel type. Suitably connected with the rotatable bolt of the lock 25 is a dog 26 arranged to operate within a recess 2'7 provided in the bar section 22 in the manner suggested in Figure 9. The free end of the dog 26 normally extends laterally of the bar section 22 and is yieldably retained in its laterally extended position through the medium of a leaf spring 28.

The free end of the dog 26 is adapted to engage the teeth of a rack 29 suitably provided within one of the grooves 21 as shown in Figure 10; and obviously when a bar 22 is in slidable engagement with a channel bar 5a, and dog 26 is projected to engage the teeth of the rack bar 29 movement of the channel bar 5a, and the bar section 22 associated therewith is positively prevented. For actuating the bolt of the lock 25 there is provided a suitable key 30.

As suggested in Figure 8 the bar sections 22 are slidably engaged with the channel bars 25 and in actual practice the guard is set within the window frame and the uprights 20, 23 are engaged behind the blind stop subsequent to an adjustment of the bar section 22 relative to the channel bars 5a as may be required due to the width of the window frame.

To remove the guard it will be first necessary to insert the keys 30 in the barrel of the lock 25 for retracting the dogs 26 thus permitting the sections 22 to be moved inwardly relative to the channel bars 5a. and in this manner reduce the width of the guard to permit 01' removal of the same from the window frame.

It is thought that the construction, utility and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exempliflcation since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It. will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. In a window guard of the class described, a plurality of vertically spaced cross bars provided intermediate their ends with a plurality of longitudinally extending slots, a plurality of uprights having oppositely twisted portions threaded through said slots, the intermediate portions of said uprights being plain for loosely fitting in the slots when a cross bar is in position with the slots receiving said intermediate portions and means-for locking said guard in operative position within a window frame.

2. In a. window guard of the class described, vertically spaced horizontal bars provided with relatively spaced slots including end slots and intermediate slots, vertical bars having oppositely twisted end portions threaded through the intermediate slots, the intermediate part of each vertical bar being fiat and having a loose fit in a slot in a horizontal bar whereby said horizontal bar can be tilted when moved to a position with its slots engaging said intermediate parts of the vertical bars, S-shaped clips having upper portions extending through the end slots, and lower portions formed with openings for receiving fastening elements, the lower portions of said clips having ends bendable reversely to engage the heads of the fastening elements.

3. In a window guard of the class described, vertically spaced horizontal bars provided with relatively spaced slots, vertical bars having oppositely twisted end portions threaded through said slots, the intermediate part of each vertical bar being flat and having a loose fit in a slot in a horizontal bar whereby said horizontal bar can be tilted when moved to a position with its slots engaging said intermediate parts of the vertical bars, apertured lips on the ends of said horizontal bars, and pins rigidly secured to said horizontal bars and having end portions extending through said apertured lips.

4. A window guard of the class described comprising horizontal channel bars, relatively fiat bars vertically arranged and having oppositely twisted end portions and substantially flat intermediate portions said channel bars having elongated longitudinally extending slots therein for receiving the twisted portions of the vertical bars, said slots loosely receiving the intermediate portions of the vertical bars to permit tilting movement of a channel bar when said channel bar is moved to a position to have its slot engage said intermediate portions of the vertical bars, an upright connecting said channel bars at one end of the latter, and a second upright connecting said channel bars at the other end thereof, said last named upright being provided with short bar sections having telescopic engagement with said channel bars, and means for locking said short bar sections against inward movement in said channel bars.
